This invention relates to sanding apparatus for power-propelled vehicles; In the use of an automobile it frequently happens that the major proportion of the 3 stretch of roadway included in a trip is relatively free or". ice, packed snow, or other material which may tend to produce skidding of the vehicle, but that there are some I, stretches of roadway throughout which the i danger of skidding is to be anticipated. Under such circumstances it is undesirable to apply chains to rear wheels of the vehicle, as it is an unpleasant task to-apply or re I move chains, and as the chains themselves become worn ai'ter having been used through- I out a certain mileage. It is, therefore, do-

sirable to provide apparatus by whichsand' may be applied to the roadway in advance of the rear wheels of the vehicle and in the 2g path to be followed them.

In utilizing sanding apparatus on an automobile it is necessary that the sand be maintained free of moisture, that the operating connections for releasing the sand to the roadway be readily accessible and operable by the driver of the automobile; and it is:

highly desirable that the container or containers for the sand, andthe means for delive rying the sand from thecontainer, be so 39 positioned and housed that their use does not materially detract from the general appear ance of the automobile. Various devices have hitherto been employed or proposed for keeping the sand in a dry condition, in

which it will flow readily, by passing exhaust gases through the sand of the container, or

by utilizing the heating effect caused by re sistance to the passage 01"- electric current.

When containers have been mounted upon 40 or under the running board of automobiles,

or in the chassis, various actuating connections for the sand releasing valve or valves have been employed, long connect-ions and special operating means being necessary because of the relatively remote positioning of the sand containers with respect to the seated position of the driver of the automobile.

I To state the nature of my invention generally, I have evolved an automobile sanding apparatus in which the containers for the sand are so formed that'they .may be;

an-d'are,'mounted within aprotective covermg formed by a'portlon of the car body.

Further, I mount them in such position that the sand is subjected to gentle heating by the engine of the automobile itself, and in such position that very short valve operating connections may be used to place the delivery of sand under thedirect control of the driv-v er of the automobile. g

The object of my invention is to provide simple sanding means, in which the sand containers are protected from excessive moisture, and are subjected to gentle heating; sanding meansiin which the connections for operating the valve or valves, to deliver the sand, are simple and efficient; and sanding means in which substantially all the apparatus is concealed within the body of the automobile, so that it does not detract from the external appearance of the automobile.

In the accompanying drawings FigureI is a fragmentary side elevation of the forward portion of an automobile, broken away in regions to show the mounting of the sand receptacles and the sand delivering means associated therewith; Figure II is a plan view showing the sand receptacles and their con nections, and indicating the outline of the automobile body in which they aremounted; Figure III is an isometric view illustrating the special form of one of the sand containers; Figure IV is a plan view of the sand-delivering valve associated with each of the containers; Figure V is a fragmentary side elevation of the forward portion of an automo bile, broken away in regions to show an alternativemount-ing of the sand receptacles and the sand-delivering means associated-therewith; Figure VI is a plan view of the for ward portion of an automobile, partly broken away to show the receptacles in plan view and the partitions to which they are attached in horizontal section; and Figure VIIis a frag.- mentary plan view "showing the structure of the operating connections and the spring for position.

In the accompanying drawings reference numeral 1 designates generally the stru-cture 2o readily from. the receptacle. As shown, twoof the automobile in which the sanding apparatus is mounted, reference numerals 2 and 3 designate respectively the hood and cowl of the automobile, and reference numeral 4 designates the steering post of the automobile.

With respect specifically to the form of my sand receptacles, I so shape these receptacles that sand may readily flow to the point of delivery therefrom, and so shape them that they may be mounted either under the hood or under the cowl of the automobile, in free space therein, and in a position in which they do not interfere with the driving of theautomobile or the comfort of a passenger. When installedeither under the hood or under'the cowl, the s and receptacles are subjected to.

gentle heating by the engine'ofthe automobile, whichbheating tends to maintain the sand in a drycondition so that it may flow receptacles 5 are employed, and are mounted under the hood ofthe automobile by. attachment to the vertical partition 6 between the hood and cowl. i

Each of the receptacles 5"comprises an upper portion 5a of rectangular contour. The

. lower portion of the sand receptacle comprises aside wall 5?), which extends vertically, and forms a direct continuation of one side wall of the upper rectangular portion 5a.

.The other side wall 50 of the receptacle, ly-

ing below the upper portion 5a of the container, is inclined verticallytoward the re- 1 gion of sand delivery. The forward end'wall 5d of the lower portionof the receptacleis inclined rearwardly to the sand outlet. 7

The general funnel shape of the receptacle permits free flow of sand to the point of sand delivery. ,The contouring of the receptacle,

moreover, performs the additional function of limiting thespace occupied by the sand receptacle as a whole; so that when two'rebracket/7, which consists of angle members having one leg thereof secured to the side of the upper portion 5a. of the receptacle, and the other leg connected to the partition 6.

At the forward endof each of the receptacles means may be applied for additionally supporting the weight of the receptacle. As shown, such means comprise bolts 8 fastened to-the forward wall of the portion 5a of each of the receptacles, to extend horizontally therefrom. Supporting connections may be made between these bolts 8 and any suitable element of the automobile body lying within thehood 2. I I

ating arm 13 of the valve plate 12 extends outwardly beyond the mounting plate 10. Through valve plate 12 are openings 14 which may be brought more or less into registry with the discharge openings ,11 in the stationary mounting plate 10 by rotation of the valve plate aboutits axis 15. From the discharge openings of each receptacle there extends a discharge pipe 16 which projects downwardly and slightly rearwardly from the discharge end of the receptacle. greater portion of this dischargev pipe 16 is housed within the hood 2, or lies behind the running board .17 of the automobile, so that a slight portion onlyof the pipe is exposed to view. Toward its rearward end discharge pipe 16 is supported from the running board by means of a bracket 18 of any suitable form. I v

Since two receptacles are desirably employed, it is convenient to interconnect their valves so that both valves may be simultaneously operated by a single actuating means. Such connecting means, as shown, comprlse a flexible shaft 19 which is mounted instraps 20 on the inclined lower side wall 50 of each] of the receptacles, and is attached at its ends in openings22 in the stem 13 of each of the valves. To the stem orarmo13 of the valve which lies nearest the steering post '4visattached a connection 23, which is terminally attached to. a handle member 24, slidably mounted in a bracket 2501i steering post 4. While this connection may be in a sense flexible, it must possess suflicient stilfness to'permit a pushing as well as a pulling action on thervalve. Similarly the interconnection 19 between the valves,rwhile flexible, must pos sless sufficient stiffness to be capable of transmitting a pushing action on the valve which The: i

is'not directly connected to operating han- V dle 24.

Figures V and VI of the drawings show identically shaped receptacles and identical parts of the automobile itself. In this moditied position of the-sanding apparatus, however, both the receptacles 5 are mounted at theirrearward ends to the inner face of partitions G by means of indentically similar brackets 7, and are disposed forwardly of dashboard 35. Their forward ends may be iently filled-by way of a ventilatoror ventilators, commonly positionedlin the'cowl of the automobile body.

' It should be particularly-notedthat the receptacles 5 in their reversed position adapt themselves equally Well to space requirements Within the bodyof the car. Thus the upper porton 5a of each receptacle is disposed above the steering post 4:, and the'cutting away of the lower portion of the-.receptacle'by incli-N nation of their 'faces 50 leaves foot room" under the cowl of the car.

Valves, and valve-operating connections,

identically similar to those shown in Figures I to IV, inclusive, of the drawings,'may .be

employed to actuate the valves of the sanding apparatus mounted in this modified portion also., I show,-however, alternative op.-

erating means to efl'ect the simultaneous actuation of the valves 12controlling the delivery conduit 16. In this modified form of actuating connections the stem or arm 13 of each of the valves is rovided with an extension 26, and connecte to each of these extensions is a flexible connector 27. The opposite terminalsof these flexible connections are attached to the ends of an arm 28, carried by a shaft 29 rotatably mounted in dashboard 35. At the inner terminal of shaft 7 29 is an operating handle 30.

By these connections the valves are simultaneously opened to the desired extent, and

areclosed by rotationof handle 30' rather than by the pushing and pulling action effected by operation of the handle 24;, shown in Figures I and II of the drawings.

As a convenient structure for assuring that the CODIIECtlOIlS. possess the necessary stifiness, while possessing suihcient flexibility. to.

that valve may desirably be employed. In either case, it is desirable to so-predetermine the force, which will be exerted by the spring, that the eiiect of the. spring will not of itself becapable of moving the valve or valves to closed position. The spring ofcourse serves to hold the valve in closed position against accidental opening caused by jolting or jarring.

The discharge pipe 31 from each ofthe receptacles is positioned in general similarity to the positioning of the discharge pipe 16, shown inFigures I and II and is supported at its rearwardextreinity by means ofbracket q portion-inclined both laterally and longi- 32 on running board 17 -It may be noted specifically.inconnection with both the discharge pipes 16 and the discharge pipes 31 that they are so curved as to comprise no abrupt bend which would impede the flow of sand from the receptacle.

This is of importance in that it permits sand to fiOWII'OJH the receptacles without the use of agitating'means, which add to the cost of the apparatus and are an element likelyto' need repair.

qThe only portion of the apparatus which is visible in. an exterior view of the automoblle isthe short length. of the discharge pipe which proj ects below the running board. If mounted under the hood 2, the sand recep .tacles are wholly hidden from view, and

if mounted'under the cowl 8, they are so positioned'as to be unobtrusive and sightly. In either mounting of the sanding apparatus the sand within the receptacles is protected from rain or snow, so that the tendency of the sand to absorb moisture is minimized. Further, in'bothinstances, the receptacles are subjected to gentle heating from the engine ofthe automobile, so that the sand is maintained in a dry condition to flow readily from the receptacles. The mounting of the sand receptacles and their valves so close to the position of the driver permits the use of short and simple valve-operating means.
